Merge tag 'net-6.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from WiFi and netfilter.

  Current release - regressions:

   - nic: intel: fix old compiler regressions

   - netfilter: ipset: missing gc cancellations fixed

  Current release - new code bugs:

   - netfilter: ctnetlink: fix filtering for zone 0

  Previous releases - regressions:

   - core: fix from address in memcpy_to_iter_csum()

   - netfilter: nfnetlink_queue: un-break NF_REPEAT

   - af_unix: fix memory leak for dead unix_(sk)->oob_skb in GC.

   - devlink: avoid potential loop in devlink_rel_nested_in_notify_work()

   - iwlwifi:
       - mvm: fix a battery life regression
       - fix double-free bug

   - mac80211: fix waiting for beacons logic

   - nic: nfp: flower: prevent re-adding mac index for bonded port

  Previous releases - always broken:

   - rxrpc: fix generation of serial numbers to skip zero

   - tipc: check the bearer type before calling tipc_udp_nl_bearer_add()

   - tunnels: fix out of bounds access when building IPv6 PMTU error

   - nic: hv_netvsc: register VF in netvsc_probe if NET_DEVICE_REGISTER
     missed

   - nic: atlantic: fix DMA mapping for PTP hwts ring

  Misc:

   - selftests: more fixes to deal with very slow hosts"
